How to Make Feminized Seeds with Colloidal Silver

We were curious how easy it was to make feminized seeds with colloidal silver at home. So we ran a little experiment and got more than 1500 viable beans without any issues. You too can do the same and make a nice stash of female plant seeds for yourself by following these step-by-step instructions.

But let’s start with a bit of theory (you can skip this part and get down to business straightaway).

What are Feminized Seeds, and How are Seeds Feminized?

In nature, cannabis plants have two distinct sexes: male and female. However, only female plants produce buds for smoking. And if these buds catch some pollen, they will be subpar in quality because they will be full of seeds and not so big and also less resinous. That’s why growers who use regular seeds must watch their plants closely and cull all males in their garden as soon as they reveal their sex. Not very convenient, is it?

It all changed with the introduction of seeds that grow into fem plants in 99% of cases. They were named feminized seeds. So, are feminized seeds always female? In the majority of cases, yes, they are guaranteed to be female. However there are ways to make fem seeds hermie, meaning they will turn male or at least produce a few male flowers inside female buds. This can happen for seeds with weak genetics, or it can be a reaction to stress.

Male Plants no Longer Necessary

And this is exactly the feature that is used for manipulating feminised plants into producing feminised seeds. You don’t need any males for that. If you use a male to pollinate a plant grown from a fem seed, the result will be a bunch of regular seeds. And if you want fem seeds only, you should use one female plant as mother and another female plant as father. Or, alternatively, you can opt for self-pollination: when a single plant is used to both produce pollen and grow seeds.

There are several methods to make a feminised plant turn male. We won’t discuss here the most barbarian one — when breeders subject their plants to high levels of stress and they are turning hermie as a result. Although, believe it or not, the first commercially available seeds were made exactly this way, back in the early 1990s. You may guess the obvious drawback of such seeds: plants grown from them often become hermaphrodites even under normal conditions.

There is a less invasive method that modern breeders use. I’m talking about spraying a plant (or an individual branch of a plant) with a colloidal silver solution. This changes the chemistry inside the plant to make fem seeds male, and does so without any stress. As a result, we get seeds on a female weed plant without making them prone to hermies.

How to Make Feminized Seeds Using Colloidal Silver Spray

First, you need to make a colloidal silver generator and use it to produce the solution for your feminized seed spray. It’s unbelievably cheap, quick, and easy. Judge for yourself by clicking the link above and reading our step-by-step guide. The result should look more or less like this:

You should start using your feminised seed spray on a plant as soon as it starts flowering. You can apply it on all branches or just one. In the latter case, cover the rest from spatter. Please remember that silver is a toxic heavy metal and can poison you. You should never smoke colloidal silver weed.

do feminized seeds produce female seeds when you use collodal silver on them

It had taken us 4 weeks before we saw clearly that male flowers began to form. It was our first experiment, and we wasted many days applying the solution with a paintbrush. Don’t do that. It’s stupid. Just cover the rest of the plant with a piece of plastic and spray the chosen branch until it’s thoroughly wet. Do it once a day.

At some point, you’ll notice little green balls appear among female hairs (pistils): first closer to the top, then further down. Continue to apply colloidal silver spray until male ‘balls’ completely oust female pistils and start to look like a bunch of grapes. Only then you can stop spraying.

can feminized seeds be pollinated? yes, look at them bananas!

And this is how another branch on the same plant looks. It was not sprayed, so it only has female flowers:

feminized seed pollination will begin soon

After another month the male flowers will turn yellow and start to open:

feminized seed pollination is already underway

Pollen Everywhere

Pollination is in full swing now, even if you don’t see the pollen. It consists of millions of tiny particles, and they fly everywhere.

Btw, pollinating buds at such a late stage of flowering is not the best idea. It would be better if the male pollen were ready a couple of weeks earlier, when the buds weren’t that mature. That would result in a) more seeds, b) less time spent, and c) better quality seeds. Well, we’re not sure about c), but some people on forums say it’s true.

When the branch with male flowers on it is fully mature, cut it, place it on a table, and rub it with your fingers until all yellow flowers fall off:

male branch from a fem plant has been cut off

Then move the flowers this way and that with a credit card. The pollen will stick to the card’s edge. Shake it off into a separate heap:

To store and later use the pollen more conveniently, you can mix it with the equal amount of flour:

you can mix pot pollen with flour

We put the mixture into an empty gelatin capsule and placed it in the refrigerator for storage..

Let me stress that we never used the pollen harvested this way to sprinkle on the plant. All pollination happened before we cut off the male branch. The seeds were fully mature 3 weeks after that. In this photo, you see only some of them. Later, we harvested at least as much.

How Soon Can You Plant Seeds After Harvesting Them?

We spent some time looking for an answer. People on forums say that the fresher the seeds, the lower germination rates. If you want to have good germination, give your homemade seeds some time to dry. Let’s say a month or two. It would be enough to degrade the hormone that prevents seeds from sprouting.

Our Experiments with Self-Pollinated Feminized Seeds

Over the next couple of years, we did a lot of experiments with our homemade seeds. The germination rates were always close to 100%, although, we must confess, we handled the process in a most off-hand manner. It’s understandable when the seeds cost you pennies.

We brought several plants to maturity and can say that they are very true copies of the parent plant. All fems, no hermies. All start to flower automatically after 2.5-3 weeks, all have the same height as the parent, the same length of the flowering period, the same structure of buds, and the same type of high. We liked the original plant, so we also liked its copies.

To Recap

Making your own feminized seeds is fairly easy. If you want to make copies of an autoflower, this is the only way. If you want to copy a photoperiod strain, it works great as well, but you also have the option of taking cuttings. Cloning marijuana is quicker, but seeds are easier to give away or sell. Believe us: with our little harvest of seeds. we’ve made a lot of people happy.


Colloidal Silver Spray For Plants: Let’s Make a Generator in 10 Min.

In this post, I’m going to teach you how to obtain a colloidal silver spray for plants using a homemade colloidal silver generator. You can assemble one with nothing but a knife and a pair of pliers. You won’t need fancy circuit diagrams, plans, or schematics because it’s just a matter of buying a few supplies in a local store, connecting them to each other, and then following our simple colloidal silver recipe.

But first let’s see why we use colloidal silver for weed plants.

Using Colloidal Silver for Weed: A Breakthrough Technology Available to Anyone

In the 1990s, cannabis breeders came up with a method of producing feminized seeds by making fem plants produce male pollen sacks. At first, the technology was unbelievably crude by today’s standards: weed plants were stressed to the point where they began to ‘hermie’ and make pollen. Of course, the seeds grown this way were also prone to become hermaphrodites (which is a nightmare for a marijuana grower).

But breeders kept experimenting and came up with several methods of turning female plants into male which didn’t involve so much stress. One of these techniques is feminizing seeds with a colloidal silver spray.

Obviously, a spray is something that you can buy online. Or, alternatively, you can buy a colloidal silver generator and make your own colloidal silver solution of premium quality whenever you like. Better still, read our instructions, and in a few hours you’ll have a colloidal silver maker that is perfectly suitable for preparing a colloidal silver fem seed spray.

Colloidal Silver Generator: 9 Volt Battery Version

Parts, Supplies, and Tools

  • A small container with a cap (I used a urine container form a drugstore)
  • A 9V battery
  • A battery connector with wires
  • 2 alligator clips
  • 2 pieces of 999 silver
  • A knife (to strip wires and cut off molten plastic)
  • A pair of pliers (to hold alligator clips while heating them)
  • A tea kettle and a cooking pot (to distill water)
  • A TDS meter (optional)

How to Make a Battery Operated Colloidal Silver Generator

Take one of the alligator clips, hold it with a pair of pliers above a gas burner and then melt two holes in the cap of the container. When the plastic cools down, cut off any burrs with a knife.

Now you can easily insert and secure the clips in these holes and clamp your pieces of silver with them.

Using the knife, strip the ends of wires and connect them to the clips. I didn’t even have to use a soldering iron. The only thing left is to connect the 9V battery. Now, our low voltage colloidal silver generator is ready for use.

I promised you that it all will take no more than 10 minutes. In fact, it took even less!

Making Distilled Water

Now comes the most time consuming part – making distilled water. According to weed forums, it’s really absolutely necessary to use distilled water and 999 silver. This will ensure that your colloidal silver liquid is pure and of the best quality.

No pictures are necessary here. Just fill the kettle with water and make it boil. Then place the cooking pot filled with cold water above the spout and at an angle. This way the drops of water condensing on the bottom can slide down the slope and drip into the container. With a rate of a drop a second, I filled my container in 10 minutes or so.

Attention! After a while, the cooking pot and the cold water inside it will warm up and the drops will be far and between. You will need to change the water in the pot several times or use ice from the freezer (as I did).

You’ll need to fill your container to such a level that, with the cap closed, the ends of silver plates are immersed, but the clips are not. The clips SHOULD NOT touch the surface!

Measuring TDS of Colloidal Silver (Optional)

I’ll make one more (optional) step to make sure that the water is really distilled. My TDS meter shows just 2 parts per million. It’s practically medical grade quality!

Now let’s connect the battery. Our constant current colloidal silver generator begins operation, making colloidal silver water.

Colloidal Silver Spray for Plants: Optimal Concentration

I don’t know of any experiments that show which concentration is best for a feminized spray. People in forums say that to achieve the necessary colloidal silver ppm for weed it’s best to leave your colloidal silver home generator working overnight. Indeed, when I measured the concentration of the solution in the morning, it was 42 PPM. I expected the liquid to be clear or maybe have a yellow color, but it was like a strong tea.

The 999 silver plates turned dark on the surface.

In later experiments, I kept my colloidal silver maker machine running for fewer hours to make the solution just a bit yellow – like weak tea. So here’s my advice: if your colloidal silver water looks like tea, it’s strong enough for feminizing seeds. And if you have a TDS meter, make sure you achieve at least 20 ppm, and you’re good to go.

And now look at our colloidal silver mist in action and the resulting bunches of male flowers that are full of pollen.
